In order to find the answer to this, we can multiply out the base factors of the trinomial using FOIL. This gives us x^2 + qx + px + pq. Next, we can combine like terms and get the base trinomial of x^2 + (q + p)x + pq. The coefficient of the x-term is therefore q + p.

Answer:
![30+15x\geq 90](https://tex.z-dn.net/?f=30%2B15x%5Cgeq%2090)
Step-by-step explanation:
Deepak charges for each Job = $30
An additional charges for working each hour = $15
Let x be the number of hours he worked for each job.
So,additional charges for working x hours = 15 x
So,he earns in total at each job = ![30+15x](https://tex.z-dn.net/?f=30%2B15x)
We are also given that He only accepts jobs if he will earn at least $90 the job.
This means he must earn $90 or more than that .
So, the inequality becomes:
![30+15x\geq 90](https://tex.z-dn.net/?f=30%2B15x%5Cgeq%2090)
Hence an inequality to determine x, the number of hours he must work during each job in order to accomplish this is ![30+15x\geq 90](https://tex.z-dn.net/?f=30%2B15x%5Cgeq%2090)
